Robert Joseph Evans updated HADOOP-8573:
----------------------------------------
Status: Patch Available (was: Open)
I forgot to add in that this patch feels like a hack to me, with loadResource
returning the properties to be added in, but I could not think of a cleaner way
to do it without completely refactoring a lot of that code. If someone else
has a better way to do this I would be very happy to switch.
> Configuration tries to read from an inputstream resource multiple times.

> Key: HADOOP-8573
> URL: https://issues.apache.org/jira/browse/HADOOP-8573
> Project: Hadoop Common
> Issue Type: Bug
> Components: conf
> Affects Versions: 1.0.2, 0.23.3, 2.0.1-alpha, 3.0.0
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans
> Attachments: HADOOP-8573.txt

>
> If someone calls Configuration.addResource(InputStream) and then
> reloadConfiguration is called for any reason, Configruation will try to
> reread the contents of the InputStream, after it has already closed it.
> This never showed up in 1.0 because the framework itself does not call
> addResource with an InputStream, and typically by the time user code starts
> running that might call this, all of the default and site resources have
> already been loaded.
> In 0.23 mapreduce is now a client library, and mapred-site.xml and
> mapred-default.xml are loaded much later in the process.
